20090177292 | CONTROL SYSTEM ACTUATION FAULT MONITORING - Methods and apparatus for monitoring and detecting failures in the actuation of a control system, such as a flight control system for an aircraft, include defining a nominal model of the control system in terms of the state variables of the control system, defining a model of an asymmetric “actuation monitoring envelope” that dynamically bounds a range that measured state variables of the system are allowed to take during operation of the system as a function of the nominal system state model, monitoring a signal corresponding to a state variable of the system during operation thereof, and detecting a failure in the actuation of the control system when the monitored signal exceeds the bounds of the monitoring envelope. | 07-09-2009 |

20090292798 | APPARATUS, SYSTEM, AND METHOD FOR COMMUNICATING CONTROL MESSAGES BETWEEN A FIRST DEVICE AND A SECOND DEVICE - An apparatus and system are provided for communicating control messages between a first device and a second device. The apparatus and system include a communication module that directs control messages between a first device and a second device through an intermediate device. The intermediate device is coupled to the first device by a control path and to the second device by a data path. The apparatus and system also include a translation module and a transmission module that cooperate to translate control messages received over the control path at the intermediate device to transport data messages and transport data messages received over the data path at the second device to control messages. Transport data messages are sent over the data path to the second device and control messages from the second device are sent over the control path to the first device. | 11-26-2009 |

20080316634 | MAGNETIC TAPE WRITE ONCE OVERWRITE PROTECTION - A magnetic tape cartridge, a recording system, and a magnetic tape drive are configured to, for example, guard against tampering with a write once overwrite protection pointer which allows a rewritable magnetic tape to be treated as write once. In one embodiment, the magnetic tape cartridge comprises a magnetic tape and a cartridge memory. The magnetic tape is configured to provide at least one overwrite protection pointer, the overwrite protection pointer identifying data to be protected from being overwritten; and the cartridge memory is configured to provide the at least one overwrite protection pointer, the overwrite protection pointer identifying magnetic tape data to be protected from being overwritten. | 12-25-2008 |

20140035778 | METHOD OF MONITORING THE INTEGRITY OF RADIO-NAVIGATION STATIONS IN A SATELLITE BASED AUGMENTATION SYSTEM - A method of monitoring the integrity of stations for observing radio-navigation signals in a satellite based augmentation system SBAS comprises: defining a geographical zone comprising a plurality of observation stations, calculating, for each observation station of the said zone and for each line of sight between the said station and a satellite, the discrepancy between the theoretical pseudo-distance D and the measured pseudo-distance D′, calculating the average m of the said discrepancies D-D′ over the said zone for at least one satellite in visibility of the said zone, validating the integrity of at least one observation station of the said zone if the said discrepancy, for the said station and for at least one line of sight between the said station and a satellite, is less than or equal to the said average that is multiplied by a predetermined exclusion threshold, and excluding this observation station in the converse case. | 02-06-2014 |
